1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
obtaining, by a sidelink hybrid automatic repeat request (HARQ) entity for transmission on a sidelink shared channel (SL-SCH), a media access control (MAC) protocol data unit (PDU) to transmit, wherein the sidelink HARQ entity is included in a MAC entity, and the MAC entity has a sidelink grant to determine a set of physical sidelink shared channel (PSSCH) durations in which transmission of the SL-SCH occurs;
storing the MAC PDU and the sidelink grant;
prioritizing a sidelink transmission of the MAC PDU over uplink transmissions if i) the MAC entity is not able to perform the sidelink transmission simultaneously with all uplink transmissions at a time of the sidelink transmission, and ii) a threshold is configured and a value of priority of a MAC control element (CE) in the MAC PDU is lower than the threshold; and
performing the sidelink transmission that is prioritized over the uplink transmission according to the stored sidelink grant.
